When you combine the stress of day-to-day living in a fast-paced environment with trying to conceive, too often romance is the first thing to suffer. The contradiction of having to time ovulation to sex versus the thrill of spontaneity that makes sex, well, sexy can easily "ruin the moment."
This is where attitude can make a difference; first, recognize that you, as a couple, are in control of what will keep those amorous fires burning. Then, turn the lack of spontaneity to your advantage: Start by making the ovulation timing secondary to when you have relations and increase frequency of your activity overall. If either or both of you are tired or "not in the mood"-adopt the "fake it till you make it" mantra. It's rare that, with both partners willing and "knowing which buttons to press," a couple can't eventually get in the mood simply by taking the time to do so. Then, for the extra important ovulation days, set the scene. Build up excitement and anticipation throughout the day by leaving each other suggestive notes. By the time you both are able to engage, excitement should be high...but a romantic, delicious meal, enticing clothing and a room set for the event beforehand will surely seal the deal.
